fix(bqjdbc): enhance logging with caller inference and explicit exception tracking

[Neenu1995]

b/505727302

• BigQueryJdbcCustomLogger.java:
  • Implemented stack trace analysis to route exact execution locations via Logger.logp().
  • Introduced Throwable interception overloads for SEVERE and WARNING tiers to print full stack traces when exceptions are thrown.
• Catch Block Instrumentation: Added explicit Logs configurations to log exceptions:
  • BigQueryConnection.java
  • BigQueryBaseArray.java
  • BigQueryBaseStruct.java
  • BigQueryParameterHandler.java
  • BigQueryDaemonPollingTask.java
  • BigQueryJdbcProxyUtility.java
• BigQueryJdbcCustomLoggerTest.java: Tests for changes made.

Note: More catch block instrumentation to follow in future PRs.

Code Review

This pull request improves error visibility across the BigQuery JDBC driver by introducing explicit logging in several catch blocks and enhancing the BigQueryJdbcCustomLogger to support caller inference and exception stack trace formatting. A new test class was also added to verify the logger's functionality. Review feedback suggests correcting a typo in the .gitignore file, optimizing the logger's caller inference, and refactoring the exception logging to use LogRecord for better integration with structured logging systems.
